CC -!- FUNCTION: Functional viral IL-10 homolog. Can bind to the human IL-10
CC receptor and compete with human IL-10 for binding sites. Requires both
CC subunits of the human IL-10 receptor complex to induce signal
CC transduction events and biological activities. IL-10 signaling pathway
CC has several immunosuppressive activities that are exploited by the
CC virus. Inhibits TLR-induced type I interferon production in host
CC plasmacytoid dendritic cells. {ECO:0000269|PubMed:15280480,
CC ECO:0000269|PubMed:19524994}.
CC -!- SUBUNIT: Homodimer; disulfide-linked. {ECO:0000269|PubMed:12093920}.
CC -!- INTERACTION:
CC P17150; Q13651: IL10RA; Xeno; NbExp=2; IntAct=EBI-1033736, EBI-1031656;
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the IL-10 family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=CAA35350.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
